Din En 60352-2 Pdf Guide
DIN EN 60352-2 is the European and German standard for solderless crimped connections. It defines the general requirements, test methods, and practical application guidelines to ensure consistent electrical and mechanical performance in electronic equipment connections. Key Specifications & Scope
The standard ensures that crimped connections remain reliable under various mechanical, electrical, and atmospheric conditions.
Primary Application: Covers solderless crimped connections made with stranded or solid wires. Essential Tests:
Pull-Out Force: Defines the minimum tensile strength required for a connection based on the wire cross-section.
Contact Resistance: Specifies how to measure and the limits for electrical resistance across the crimp.
Mechanical Integrity: Includes guidelines for insertion/removal of contacts and bending of wire bundles.
Manufacturer Guidance: It strongly recommends using tools and crimp contacts from the same manufacturer to guarantee high-quality workmanship. Document Status & History
The standard is a German adoption of the international IEC 60352-2 standard. IEC 60352-2:2006 - iTeh Standards
The DIN EN 60352-2 standard is the European adoption of the international IEC 60352-2 standard, which governs the technical requirements and testing procedures for solderless crimped connections. din en 60352-2 pdf
Because this is a copyrighted technical document, a full "DIN EN 60352-2 PDF" is typically only available for purchase through official standards bodies like DIN (Deutsches Institut für Normung) or Beuth Verlag. However, the following informative overview outlines the critical engineering requirements and testing protocols defined within the standard. 1. Scope and Application
The standard applies to solderless crimp connections made with stranded wires from or solid wires from
in diameter. It is primarily used in telecommunications, industrial electronics, and automotive wiring to ensure electrical continuity and mechanical stability without the use of solder. 2. Key Technical Requirements
To comply with DIN EN 60352-2, a crimp connection must meet specific physical criteria:
Deformation: The crimp barrel must be sufficiently deformed to compress all wire strands into a gas-tight mass, preventing oxidation.
Wire Position: The conductor must be visible at the front end of the crimp barrel (the "brush"), and the insulation must be properly supported by the insulation crimp without entering the electrical connection zone.
Material Compatibility: The standard specifies that the crimp barrel and the wire should have compatible finishes (e.g., tin-plated) to prevent galvanic corrosion. 3. Essential Testing Procedures
The standard defines several tests to validate the quality of the connection: DIN EN 60352-2 is the European and German
Tensile Strength (Pull-out Force): One of the most critical tests. It defines the minimum force (in Newtons) required to pull the wire out of the crimp. For example, a wire typically requires a minimum pull-out force of
Contact Resistance: Measures the electrical resistance across the connection. It must remain below a specified milliohm ( ) threshold even after environmental aging.
Microsection Analysis: A destructive test where the crimp is cut cross-sectionally and polished. Engineers look for "voidless" compression, where no air gaps remain between the wire strands. 4. Why Compliance Matters Using DIN EN 60352-2 compliant connections ensures:
Long-term Reliability: Resistance to vibration and thermal cycling.
Safety: Prevention of overheating caused by high contact resistance.
Interchangeability: Consistency across different manufacturers of crimp tools and terminals. 5. Accessing the Document
If you require the specific tables for pull-out forces or contact resistance for your wire gauges, you can find them in the official document versions:
Current Version: DIN EN 60352-2:2014 (or the latest amendment). English Equivalent: BS EN 60352-2 or IEC 60352-2. Scope and intended use
Scope and intended use
- Applies to soldered connections used in electronic equipment and electrical apparatus where permanent joints are required.
- Intended for manufacturers, quality engineers, test labs, and designers who need standardized test methods to qualify solder processes, assembly techniques, and joint designs.
- Useful for process control, failure analysis, supplier qualification, and conformance testing in production and development environments.
Step 5 – Documentation
Keep the PDF in a controlled folder (e.g., SharePoint, QMS software). When an auditor asks, "How do you know your crimps are good?" – you point to a work instruction that says "Per DIN EN 60352-2, Clause X."
1. Instant Searchability
A physical 40-page document requires flipping. A PDF allows you to hit Ctrl+F and search for terms like "pull force," "voltage drop," or "strand diameter."
1. Confusing "Crimp" with "IDC" or "Wrap"
DIN EN 60352-2 only covers crimped connections. For Insulation Displacement Connections (IDC), see DIN EN 60352-3. For wire wrapping, see Part 1.
4. Missing the "Practical Guidance" Annex
Unlike many dry standards, DIN EN 60352-2 includes an informative annex with photos of good vs. bad crimps. Many users skip it, but it is the most valuable section for training operators.
Q4: My customer requires "DIN EN 60352-2". Do I need to buy it or can I just test to it?
A: To legally claim compliance, you must have a licensed copy. Auditors may ask to see your referenced version. Using a pirated PDF puts your certification at risk.
Step 3 – Test Plan
Write an internal test plan that references specific clauses:
- Clause 6.2 – Tensile test frequency (e.g., every shift, first piece).
- Clause 8.3 – Microsection frequency (e.g., weekly).
- Clause 9 – Re-test after tool maintenance.
Q3: Does this standard cover automotive battery terminal crimps?
A: Partially. For high-current (e.g., >100A) or very large gauge wires (>35 mm²), consult ISO 6722 or LV 214 (automotive specific). DIN EN 60352-2 covers typical electronics up to 10 mm².
